5-50t/D Bio-Diesel Equipment

Biodiesel
Biodiesel is typical "green energy resource", is made from soy and rapeseed oil crops, oil palm and pistacia chinensis bunge oil fruit, microalgae Oil aquatic plants and animal oil, waste edible oil as raw material. Developing biological diesel oil for sustainable economic and social development, Optimize energy structure, reduce pressure of environment has important strategic significance.
Compare with normal diesel, biodiesel is good for environment protection.


Energy-Saving and Environmental Protection bio-diesel technology
1. Dry method degumming and pre-bleaching technology
It reduces the lost of neuter oil for 50%; Saving the clay for 40-50%, which improve the yield.
2. Dry-washing to replace the water washing technology
It adopts MeSiO4 for the dry-washing catalyst to replace the water, to get the better quality bio-diesel than water-washing method.
This technology does not produce any waste water for saving more investment, so not any pollution.

Introduce of technology
(for the example: Rapeseeds oil)

Main process
Twice time Reacting step
Rapeseed oil and methanol, catalyst in caustic soda existence condition happened methyl continuous change. After two level methyl ester reaction go to the water washing process, which get the pure Methyl ester.

Rape oil heated add into the methanol and catalyst on the first level reaction, parts of the fatty acid is changed into the methyl. This level of rapeseed oil was almost a methyl ester changed, The mixture of glycerol and methanol, methyl ester continuously is bringed out. Use one Centrifuge to separate the mixture of the first level reaction. Separate the rape oil/methyl ester and glycerol/methanol mixture. Methanol and glycerol in the subsequent process is recovery. In the second reaction of methyl further change the rape oil into methyl ester with adding the methanol and cyclast. Use the second Centrifuge to separate the two phase.

Recovery of methanol
The residual methanol of Rape oil methyl ester is removed out and back to the process through evaporation.

Refinery of the Glycerin
Each production 10 tons of biological diesel, it can produce 1 ton of crude glycerin.
It is very necessary for refining the glycerin for increasing the yield.

The characteristic
Due to the reaction is divided into two steps, each reaction generated glycerin is centrifugal separation, methyl ester reaction degree can be more than 99%.

Capacity: 30-500t/24h
